Efficiency Comparison Between Rivian R2 Performance and Tesla Model Y Performance

The Rivian R2 Performance matches the Tesla Model Y Performance in combined EPA efficiency at 105 MPGe and 32 kWh/100 miles according to official figures. However, real-world efficiency tests show the R2 consumes 18% to 26% more energy than the Model Y across all tested speeds. The R2’s heavier chassis and less aerodynamic shape impact its on-road consumption. In fast charging, the R2 sustains 600 amps up to 32% state of charge, reaching 229 kW, but the Model Y outperforms the R2 in cruising efficiency and miles per kWh after fast charging due to its aerodynamic profile and lighter weight.

• Rivian R2 and Tesla Model Y match 105 MPGe combined EPA rating
• R2 uses 18-26% more energy than Model Y in real-world tests
• R2 charges at 600 A up to 32% and 229 kW, better than Model Y
